While “at least” represents a minimum quantity in its literal meaning, “at most” is the opposite — it is the maximum or highest amount. It is another way of saying “no more than.”. Anything under the stated number is correct, acceptable, or makes a statement true.In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.. Functions were originally the idealization of how a varying quantity depends on another quantity. For example, the position of a planet is a function of time.Functions can be injections (one-to-one functions), surjections (onto functions) or bijections (both one-to-one and onto). Informally, an injection has each output mapped to by at most one input, a surjection includes the entire possible range in the output, and a bijection has both conditions be true. This concept allows for comparisons between cardinalities of sets, in proofs comparing the ...Complex Numbers in Maths. Complex numbers are the numbers that are expressed in the form of a+ib where, a,b are real numbers and 'i' is an imaginary number called "iota". The value of i = (√-1). For example, 2+3i is a complex number, where 2 is a real number (Re) and 3i is an imaginary number (Im). Combination of both the real number ...t. e. In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. [1] The set X is called the domain of the function [2] and the set Y is called the codomain of the function. [3] Functions were originally the idealization of how a varying quantity depends on another quantity.Sometimes in math we describe an expression with a phrase. For example, the phrase. " 2 more than 5 ". can be written as the expression. 2 + 5 . Similarly, when we describe an expression in words that includes a variable, we're describing an algebraic expression (an expression with a variable). For example,

3. Departing a little from the other very good answers here. Strictly speaking, nabla is the name of the typographical glyph, the upside down triangle: just a symbol on paper, meaning whatever the author intends it to mean. The name comes from the glyph's resemblance to an old fashioned harp.In mathematics, a prime number is any whole number greater than one that has no positive factors other than one and itself. For example, the number 17 is prime, because its only factors are one and 17.This glossary contains words and phrases from Fourth through Sixth Grade Everyday Mathematics.

This means that these complex numbers are actually just real numbers, and can be written as a + 0i, or simply a.In mathematics, there are multiple sets: the natural numbers N (or ℕ), the set of integers Z (or ℤ), all decimal numbers D or D , the set of rational numbers Q (or ℚ), the set of real numbers R (or ℝ) and the set of complex numbers C (or ℂ). These 5 sets are sometimes abbreviated as NZQRC.

In a data set, the mode or modal value is the value or number with high frequency or more appearance frequently. Apart from the mean and median, it is one of the three measures of central tendency. We can analyse the modal number meaning as the most ...

Sets can themselves be elements. For example, consider the set . The elements of B are not 1, 2, 3, and 4. Rather, there are only three elements of B, namely the numbers 1 and 2, and the set .Solved Examples on Scale. Example 1. Find the scale factor when a square of side 4 cm is enlarged to make a square of side 8 cm. Solution: The formula for scale factor is: Scale Factor = Dimensions of New Shape/Dimension of Original Shape. Therefore, the scale factor for the given enlargement is. Scale Factor = 8 / 4.The capital Latin letter Z is used in mathematics to represent the set of integers.

In a wide sense, as argued below, the answer is no. Indeed, R(z) ℜ ( z) is not a holomorphic function since its image is the real line. In this sense, there is no formula for R(z) ℜ ( z) that does not involve z¯ z ¯, because the Cauchy-Riemann equations fail for R(z) ℜ ( z) : This was said already in the comments.
